摘要
1992-2008年,在云南省耿马县城区海拔1 100 m地区农田设置系统监测点,研究害鼠种类及发生消长规律。结果表明,农田害鼠以黄胸鼠为绝对优势种群,占17年所捕获害鼠总数的83%,近4年所捕害鼠全为黄胸鼠。年内捕获率和繁殖力出现双峰,与田间为害高峰相吻合。雌雄性比为1∶1.8,雄性多于雌性。以成体组捕获率最高,占总捕鼠数的50%;幼体组和亚成体组次之,分别占21%和20%。根据年内消长规律,确定化学统一灭鼠时间为4月中旬和10月底的干季。宜选用敌鼠、溴敌隆、氯鼠酮、氟鼠灵等,以稻谷作饵料为好。
The species and occurrence of pest rodents were studied in Gengma during 1992-2008. The results showed that Rattus flavipectus was absolutely the dominant species in the farmland, accounting for 83% of the total number of captured rodents during the 17 years, and all rodents caught were R. flavipectus in nearly four years. There were two peaks in the catch rate and fecundity. Male and female sex ratio was 1：1.8. The most catches were adults, accounting for 50% of the total, followed by larvae and sub-adults, accounting for 21% and 20%, respectively. Based on the population fluctuation during the year, a unified anti-rat campaign at the end of the dry seasons （mid-April and the end of October） was suggested. Diphacine salt, bromadiolone, green chlorophacinone and flocoumafcn should be used with rice grains as baits.
